Converting and array

Question

I have an arr like this

[{
    "ID": "this THE ID",
    "NAME": "this THE NAME",
    "AGE": "thiS THE AGE"
}, {
    "ID": "that ID",
    "NAME": "that THE NAME",
    "AGE": "that THE AGE"
}]

I'm looking to achieve this result:

[["this THE ID","this THE NAME","thiS THE AGE"], ["that ID","that THE NAME","that THE AGE"]]

What i tried

var result = []
data.forEach(function(ID,NAME,AGE) {
  result.push(ID)
  result.push(NAME)
  result.psuh(AGE)
});

But i am not getting the correct result that i wanted

Map is your best friend in those kind of situation

 var arr = [{
        "ID": "this THE ID",
        "NAME": "this THE NAME",
        "AGE": "thiS THE AGE"
    }, {
        "ID": "that ID",
        "NAME": "that THE NAME",
        "AGE": "that THE AGE"
    }]
 
 const result = arr.map(({ID,NAME,AGE}) => [ID,NAME,AGE]);
console.log(result)

You could map the values, assuming you want the values in insertation order.

var array = [{ ID: "this THE ID", NAME: "this THE NAME", AGE: "thiS THE AGE" }, { ID: "that ID", NAME: "that THE NAME", AGE: "that THE AGE" }],
    result = array.map(Object.values);

console.log(result);

Your function need a destructuring assignment for the properties and you could push an array with the values.

var array = [{ ID: "this THE ID", NAME: "this THE NAME", AGE: "thiS THE AGE" }, { ID: "that ID", NAME: "that THE NAME", AGE: "that THE AGE" }],
    result = [];

array.forEach(function({ ID, NAME, AGE }) {
    result.push([ID, NAME, AGE]);
});

console.log(result);

You almost there:

You need to create a nested array for each iteration.
You need to destructure the values as follow: function({ID,NAME,AGE}){...}

var data = [{    "ID": "this THE ID",    "NAME": "this THE NAME",    "AGE": "thiS THE AGE"}, {    "ID": "that ID",    "NAME": "that THE NAME",    "AGE": "that THE AGE"}];

var result = []
data.forEach(function({ID,NAME,AGE}) {
  result.push([ID, NAME, AGE] /*Nested array*/);
});

console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }

Using the function map:

var data = [{    "ID": "this THE ID",    "NAME": "this THE NAME",    "AGE": "thiS THE AGE"}, {    "ID": "that ID",    "NAME": "that THE NAME",    "AGE": "that THE AGE"}];

var result = data.map(function({ID,NAME,AGE}) {
  return [ID, NAME, AGE];
});

console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }

And the shortest, using arrow function:

var data = [{    "ID": "this THE ID",    "NAME": "this THE NAME",    "AGE": "thiS THE AGE"}, {    "ID": "that ID",    "NAME": "that THE NAME",    "AGE": "that THE AGE"}];

var result = data.map(({ID,NAME,AGE}) => ([ID, NAME, AGE]));
console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }

You may do as follows;

var arr = [{ "ID": "this THE ID",
             "NAME": "this THE NAME",
             "AGE": "thiS THE AGE"
           },
           { "ID": "that ID",
             "NAME": "that THE NAME",
             "AGE": "that THE AGE"
           }],
    brr = arr.map(Object.values);
 console.log(brr);
